1 Day Acuvue Moist 90 for Astigmatism lenses are soft daily disposable contact lenses and are used to correct corneal irregularities. They are made from etafilcon A with a water content of 58% and the wetting substance povidone (artificial tears), and are therefore excellent for dry eyes. The patented Hydraclear Technology used to make them means the wearer's eyes are supplied with a balanced mixture of moisture and oxygen, thanks to a particularly moisture rich wetting agent. Another benefit of 1 Day Acuvue Moist for Astigmatism lenses is the fact that they have 99% UV B and 86% UV A filters, which protect the cornea and the inner eye from harmful UV radiation.
